@debera – The uses of this product is enormous, now you no longer need to carry your travel charger or extra battery pack where ever you go. It's also great if this power could be stored on a power bank for later use.
Elizabeth, can't this principle use the other way around, where the flow will harvest the energy according to the movement of the peoples. If it is applicable it may be harvest more power to a specific work. Like lighting street lamps ..........etc.
Elizabeth this is really really interesting article, these are the innovations that we need in the future. I believe that if each person can produce their day today energy need there want be a much energy issue. This is the ideal way to start that cause that whether we like it or not we walk every day.
"DARPA's effort to harness 1–2 watts from continuous shoe impact while walking were abandoned due to the impracticality and the discomfort from the additional energy expended by a person wearing the shoes. Other energy harvesting ideas include harvesting the energy from human movements in train stations or other public places"
Looks like someone has tried this before.
I would guess that piezo output characteristics are less suitable to battery charging than the generator. Looks like piezo's are good for very high voltages, which is probably not what you want to charge a cell phone battery.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
